Abstract

The present invention relates to a structure of a solar heat and sunlight composite device. More specifically, by covering part of the top of a solar heat collector by moving a solar module from the bottom to the top, the solar heat collector can be protected from overheating while maintaining the function as a solar heat collector. Furthermore, since only part of the solar heat collector, not the whole, is covered, the moving distance of the solar module can be reduced. A mirror is combined to the end of the solar heat collector using a hinge and the mirror inclines toward the top using an elastic spring as the solar module moves toward the top of the solar heat collector so that the sunlight reflected from the mirror is concentrated on the solar module, thereby increasing the amount of sunlight and accordingly raising the output of the solar module.

Conventional techniques for the utilization of such solar energy can be largely divided into a form of power generation using solar light and hot water using solar heat. Photovoltaic power generation has been researched and commercialized in developed countries and domestic countries, and research is being conducted to improve efficiency and high quality. In the case of solar heat, it absorbs solar radiation and produces hot water, and uses the hot water to supply building heating and hot water. The solar system collects the solar heat in the daytime and stores it in the hot water in the heat storage tank, and uses the hot water stored in the heat storage tank when necessary.

However, when exposed to the sun for a long time, the solar system is overheated, there is a problem that the internal failure and malfunction.

In order to solve the above problems, the PV module is covered over the entire upper part of the solar system to cool down the heat of the overheated solar system. do.

However, since the solar module covers the entire upper part of the solar system, the solar system cannot function during the period, causing a problem in the production of hot water, and thus, the efficiency of the system is lowered.
